The invention discloses a high wear-resisting oil pressure jacking rod machining process. The high wear-resisting oil pressure jacking rod machining process comprises the following steps of SKD61 rawmaterial preparing, center oil hole drilling, outline and auxiliary thread CNC rough lathing, heat treating, jacking center jig tightening and equipping, outer circle rough grinding, seal ring grooveCNC finish lathing, nitrocarburizing, outer circle and end surface finish grinding, jacking center jig dismantling and flat grinding to control the total length, inner hole CNC finish lathing (to remove the auxiliary thread), outer circle polishing and ultrafine MAX coating. According to the high wear-resisting oil pressure jacking rod machining process, SKD61 raw materials are selected and used as base materials to perform machining, by means of 'overall hard quenching and nitrocarburizing' treatment, a jacking rod is made to have the characteristics of outer hardness and inner toughness to achieve the requirements for jacking rod wear resistance and impact resistance, and by means of configuration of jacking center auxiliary datum, a jacking rod outer circle and a mold installation surface are machined in place in a same work procedure, so that the fact that the materials can also meet the jacking rod machining precision requirements even if large deformation is generated after heattreatment is guaranteed.
